Abstract

Using a new universal distribution called switch distribution, we reveal a prominent statistical difference between a text in natural language and its unigram version. For the text in natural language, the cross mutual information grows as a power law, whereas for the unigram text, it grows logarithmically. In this way, we corroborate Hilberg’s conjecture and disprove an alternative hypothesis that texts in natural language are generated by the unigram model.

一种新的通用代码有助于区分自然语言和随机文本
使用一种新的称为开关分布的通用分布,我们揭示了自然语言文本与非语言文本之间的显著统计差异。对于自然语言文本,交叉互信息呈幂律增长,而对于单字母文本,交叉互信息呈对数增长。通过这种方式,我们证实了Hilberg的猜想,并反驳了另一个假设,即自然语言中的文本是由一元模型生成的。
